Signifyd protects millions of transactions daily.

The best technology. The happiest customers.

“With Signifyd, we’ve been able to increase revenue by 15% by selling into markets that we were previously cautious about. We’ve done this while simultaneously keeping chargebacks very low and reducing manual reviews by 80%. Signifyd has been a terrific ally in growing our business!”

Ahmed Khattak

CEO, GSMNation

“If you are worried about Chargebacks, decline a lot of international transactions, or are spending too much time reviewing transactions, I'd highly recommend their service. We've used other fraud services before, but we've not seen anything as simple with all the rich information returned."
